Graphene yog exfoliated los ntawm Redke graphite cov khoom siv, ob-seem crystal muaj cov pa roj atoms uas tsuas yog ib qho atomic tuab. Vim nws cov khoom siv hluav taws xob zoo, hluav taws xob thiab cov neeg kho tshuab, graphene muaj ntau cov kev siv. Yog li yog flake graphite thiab graphene ntsig txog? Cov hauv qab no ua plaub ntsuab Editor Analitor Analyzes kev sib txheeb ntawmFig Kas graphitethiab graphene:
1. Cov kev rho tawm ntawm cov txheej txheem huab hwm coj ntau yam tsis tau los ntawm Flake Graphite, tab sis los ntawm carbon-muaj roj xws li methane thiab acetylene. Txawm hais tias lub npe muaj lo lus graphite, kev tsim cov graphene tsis yog muab tau tshwj xeeb los ntawm flake graphite. Hloov chaw, nws tau los ntawm cov pa roj carbon-muaj xws li methane thiab acetylene. Txawm tias txoj kev tshawb nrhiav tam sim no tau muab rho tawm los ntawm tsob ntoo cog ntoo, thiab tam sim no muaj ib txoj kev rho tawm graphene los ntawm cov ntoo tshuaj yej.
2. Graphite flakes muaj ntau lab graphene. Graphene yeej muaj nyob rau hauv qhov. Yog tias muaj kev sib raug zoo ntawm graphene thiab flake graphite, ces graphene yog superimposed txheej los ntawm txheej rau cov duab fl graphite flakes. Graphene yog ib qho me me ib txheej txheej txheej. Nws tau hais tias ib millimeter ntawm flake graphite muaj txog 3 lab txheej ntawm graphene, thiab kev sib kis ntawm graphene tuaj yeem pom. Txhawm rau siv piv txwv, cov lus peb sau rau ntawm daim ntawv nrog xaum muaj ob peb lossis kaum tawm ntau txhiab tus txheej ntawm graphite. Ene.
Cov txheej txheem rau kev npaj graphene los ntawm Fedake Graphite yog yooj yim, muaj pes tsawg leeg, thiab cov nqi qis, thiab yog qhov haum rau kev tsim khoom loj.
